The paper focuses on two key molecular players in the story of influenza infection: a human protein called TRIM25, which was recently discovered to play an important role in the human immune response to flu infection; and a protein called NS1 present in all strains of the influenza A virus and shown to bind TRIM25 to keep it from doing its job.

The vaccines targeted an influenza A H1N1 seasonal flu strain as well as A (H7N9), a virus considered to have the potential to trigger a human pandemic.

In natural settings, pigs can act as a virtual mixing bowl to combine avian - and mammalian - specific influenza strains, potentially allowing avian strains to better adapt to humans.

The human influenza virus H1N1 that caused the 2009 flu pandemic, and H9N2, an avian influenza virus that is endemic in bird populations in Asia, are close cousins — close enough that they can swap genes if they find themselves in the same cell, resulting in new viruses that are a patchwork of the parent strains.

To cross the species barrier and establish themselves in the human population, influenza strains must acquire mutations that allow them to evade components of the human immune system, including, perhaps, the innate immune protein MxA.

This protein can protect cultured human cells from avian influenza viruses but is ineffective against strains that have acquired the ability to infect humans.
